The San Francisco 49ers kicked off a three-day minicamp on Tuesday. It consists of two days of practices, the first of which took place on Tuesday. The third day will be for the players to have fun with their families at the team facility.

Head coach Kyle Shanahan's father, Mike, was on hand for Tuesday's practice. He watched from the sideline alongside general manager John Lynch.

Below are some notes from Tuesday's practice.

Dante Pettis

Rookie wide receiver Dante Pettis had a nice outing, according to Matt Barrows of the Sacramento Bee. He had five catches, including a 30-yard completion down the sideline from quarterback C.J. Beathard while working against defensive back Terrell Williams. Four of Pettis' receptions came during 11-on-11 drills.

You don't necessarily have to be a big receiver to be a red zone threat. Nearly 20% of Pettis' receptions over his last two years at Washington resulted in TDs. https://t.co/dHvDBwQRts

While Pettis' deep reception did not result in a touchdown, wide receiver Aaron Burbridge finished the drive with a score, according to team reporter Joe Fann.

Richard Sherman

Richard Sherman's temporary job as an assistant coach ended on Tuesday when the cornerback was allowed to participate in individual drills. He is coming off of a ruptured Achilles suffered in November while with the Seattle Seahawks. Sherman is not expected to be a full participant in practices until training camp in late July at the earliest.

Cornerbacks

Tyvis Powell and Tarvarius Moore rotated at the cornerback spot opposite second-year starter Ahkello Witherspoon, according to Nick Wagoner of ESPN. Powell was able to haul in an interception off quarterback Jimmy Garoppolo.

It's amazing the difference a year makes. Ahkello Witherspoon looks like one of the most confident dudes on the field. Constant bounce in his step. Always jamming to the music. Carries himself with a new swag.

Running Backs

Running back Joe Williams fumbled the football following a strip from linebacker Mark Nzeocha, according to Matt Maiocco of NBC Sports Bay Area. Before practice, Shanahan shared how impressed he has been with Williams' improvement since last year.
